RAI LWAY-CROSSING.

SPECIFICATION forming part of Letters Patent No. 229,865, dated July 13,1880.

Application filed June 4, 1880. (No model.)

reference being had to the accompanying drawings, and to letters orfigures vof reference marked thereon, which form apart of thisspecification.

My invention relates to devices for connecttaining my invention. Fig. 2is a like view of one of the chairs, and chair and rails.

In the above-named drawings I have represented a crossing consisting oftwo single lines of railway intersecting each other at right an- Fig. 3a section of the gles; but my invention is applicable to railways havingtwo or'more tracks and crossing each other obliquely, and my invention,while represented asapplied to a horse-railway track, is applicable tosteam railways with equal benefit. I 1 I AA B B represent the sidetimbers or stringers of two intersecting horse-railway tracks, the railsof such tracks being shown at a a b b,

respectively. At each point of intersection of the timbers A A B 13,1employ a chair, 0, composed of a flat plate in the form of a Maltesecross,'thecentral portion and each arm of such cross 0 d d d at being ofa width equal to that of the stringers, the central portion covering thepoint'of intersection of the stringers and the armsbeing let into rabbete, &o.,

in the adjacent upper faces of the stringers, and being preferablysecurely bolted thereto.

Each arm d has side ledges, f, to provide a groove to receive the endsof a rail, and each arm, or so many of them as may be deemed advisable,has a vertical ear, g, depending from it to overlap the contiguous faceof a stringer and aid in strengthening the joint between the stringers.

In addition to the ledges f, &c., before named, each chair has a ledge,h, crossing it at right angles, the upper surface of this ledge beingflush with the bottom of the flangegroove i in the rail, and being sosituated as to coincide with the flange-groove of each rail of one lineoftrack, and serving to separate the ends of the rails of the othertrack sufliciently to form an intervening groove, k, which is acontinuation of the groove of the rails. (See Fig. 3.) J

- In laying a crossing in accordance with my invention the stringers arefirst jointed and rabbeted and then laid in place. The chairs are nowapplied, as shown in the drawings, and the railslaid in place. In thepresentinstance the intermediate ledge, h, is at right angles to thelongest plane of the rails a, a; hence it separates the meeting ends ofthese rails and provides the channel It, before named, to permit ofpassage of the flanges of the wheels which may be traveling upon therails b b, such ledge h and channel It being coincident with thefiange-groovesi of said rails b b. After the chairs have been appliedand secured to the stringers, as stated, a short piece of rail is laidupon the stringers B, and-between and abutting at opposite ends againstthe ledges h h, and the main rails of the track are then laid with theirends also abutting against the ledges. A short piece of rail is now laidupon each stringer A, and between and abutting at opposite ends againstthe inner faces of the rails a and, finally, the main rails of thistrack are laid with their ends abutting, respectively, against the outerfaces or edges of the rails a.

The chairs which constitute the subject of my invention arecomparatively light, cheap, and easily transported, and in laying acrossing with them only the ordinary rail need be used.

I claim- 1. A chair for covering the point of inter- B, the chairs 0,eountersunk'in said timbers, and provided with ears or flanges g, for embracing said timbers and binding them in place, substantially as setforth.

In testimony whereof Iaffix my signature in' :5 presence of twowitnesses.
